Battle Born BB10012 100Ah 12V LiFePO4 Deep Cycle Battery
12 V 100 Ah LiFePO4 battery, 14.06 kg, with a 100 A BMS, a 200 A 30-second surge, 100% usable depth of discharge, IP65, brass flag terminals, and a 10-year warranty. Drops into a Group 27 or Group 31 tray. No cycle-life figure is published with a depth-of-discharge basis, so none is recorded.

A battery is a component, not a power supply. Rated capacity is measured at a stated discharge rate and temperature (shown below where the manufacturer publishes it). Real usable energy is lower and depends on the depth of discharge you run the pack to, the load, the temperature and the inverter it feeds. This index publishes rated figures only and derives no single "real usable watt-hours" number. On its own a bare
battery has no inverter, no charge controller and no AC outlet: it stores energy for a system you
build around it, and its safe charge and discharge limits (in the specifications below) are part of
that system design.

This is Battle Born's BB10012, the non-heated standard version of its 100 Ah 12 V lithium iron phosphate battery, and a US-assembled alternative to the Renogy and LiTime packs indexed here. Its battery management system holds continuous discharge to 100 A and continuous charge to 50 A, and allows a 200 A surge for 30 seconds, a materially longer surge window than the 1 to 10 second ratings common elsewhere in this family. Battle Born publishes a 100% usable depth of discharge as a specification, which is unusual: most manufacturers quote a recommended DoD of 80%. It weighs 14.06 kg, carries an IP65 rating, and uses brass flag terminals with a 3/8 in hole torqued to 9 to 11 ft-lb, rather than the M8 studs common on this family. Up to four units may be wired in series, and Battle Born states there is no limit on parallel connections. It ships no charge controller or inverter. The warranty is 10 years, the longest in this family. One figure is deliberately absent: Battle Born advertises 3,000 to 5,000 cycles and 100% depth of discharge as separate claims and never states cycles at a given depth of discharge, so this index records no cycle-life number rather than pairing two unlinked figures.
Variant note: BB10012, the Non-Heated / Standard version, and the only purchasable variant on this product URL. Distinct from the BB10012H heated version and the BB10012i Smart (Bluetooth) version, which are separate SKUs. Battle Born's own documentation notes that the Class I Division 2 listing does not apply to the heated version, which confirms the non-heated model is a genuinely different product rather than a label.
Data note: Figures taken from Battle Born's official datasheet PDF and product manual on 2026-08-15 (SKU BB10012, the single purchasable variant on this URL: 'Non-Heated / Standard'). CHARGE TEMPERATURE CONFLICT, resolved and preserved: the manual's Temperature Specifications block prints 'Charge Temperature | 25°F to 135°F' and is the only row in that block with no Celsius equivalent, while the same manual states 'Battery Charge Temperature Range 32°F to 131°F (0°C to 55°C)' and 'Cell Charge Temperature 32°F to 131°F (0°C to 55°C)', and its BMS section states 'The BMS will not allow a charging current under 32°F (0°C)'. The 0 C to 55 C window is published verbatim in Celsius, corroborated three times, and matches the enforced BMS behaviour, so it is the recorded value; the 25°F row is noted here rather than silently dropped. Recording a sub-zero charge floor would have asserted charging at a temperature the manufacturer says the BMS blocks. nominalVoltageV is recorded as 12 because Battle Born publishes '12 Volt' and does not print a 12.8 V nominal anywhere; this index does not infer one for it, which is why this record differs from the LiFePO4 packs whose manufacturers state 12.8 V. capacityWh is null: no watt-hour figure appears in the datasheet, the manual or the product page, and it is not computed. recommendedChargeA is null: Battle Born publishes a recommended charge as a C-rate (0.5C) rather than an ampere value, and converting it would require multiplying by capacity. maxInParallel is null because the manufacturer states no limit rather than a number, and 'unlimited' is not a value this numeric field can carry; the statement itself is preserved in seriesParallelSupport. terminalTorque is stored as published in ft-lb only; a newton-metre equivalent is not published. Weight and dimensions are unit conversions of the published 31 lb and 12.76 x 6.86 x 8.95 in, with the source units preserved in the raw claims; the weight is independently corroborated by the store's own variant data (14,061 g). bciGroupSize is supported by product prose and product tags rather than a spec-table row: the manual has no group-size row, so the value is recorded with that caveat.
Specifications
Chemistry, nominal voltage, rated capacity and weight come from official manufacturer sources;
the exact claims and links are in the provenance table. Peak
(surge) discharge is always shown with the seconds it is rated for and is never presented as the
continuous rating, and any cycle-life figure is shown with the depth of discharge it is quoted
at. Figures the manufacturer does not publish are left blank rather than estimated.

Use cases
RV, marine or off-grid house battery dropping into a Group 27 or Group 31 tray
Loads with a heavy inrush, where the 200 A surge held for a full 30 seconds matters more than a higher but 1-second surge
Long-horizon installs where a 10-year warranty and 100% usable depth of discharge drive the sizing
Strengths and weaknesses
Strengths
200 A surge rated for 30 seconds, a far longer window than the 1 to 10 second surge ratings elsewhere in this family
100% usable depth of discharge published as a specification rather than a recommended 80%
10-year warranty, the longest of any battery in this index
No manufacturer limit stated on parallel connections, so banks scale without a published ceiling
Weight is triple-sourced (datasheet, manual and the store's own variant data all give 31 lb / 14.06 kg)
Weaknesses
No cycle-life figure can be published here: Battle Born states cycles and depth of discharge as unlinked claims, so this index records neither rather than pairing them
No rated watt-hour figure is published anywhere in the datasheet, manual or product page
Maximum continuous charge current is 50 A, half the 100 A that the Renogy and LiTime 100 Ah packs accept
No self-heating: the BMS blocks charging below 0 C
14.06 kg is the heaviest 100 Ah LiFePO4 in this index
No Bluetooth monitoring on this version (Battle Born sells a separate Smart variant)

Official datasheet (PDF) — Battle Born publishes '12 Volt' and does not state a 12.8 V nominal on the datasheet, manual or product page. The published figure is recorded rather than inferring the 12.8 V typical of a four-cell LiFePO4 pack.
Battery Charge Temperature Range | 32°F to 131°F (0°C to 55°C)
Official datasheet (PDF) — Published in Celsius verbatim and corroborated three times, including the BMS statement that charging is blocked below 0 C. A conflicting 25°F row elsewhere in the same document is recorded in notes rather than used.

The BMS will not allow a charging current under 32°F (0°C) but will continue to discharge down to -4°F (-20°C).

Weight | 31 lbs.
Official datasheet (PDF) — Published in pounds; 31 lb converts to 14.06 kg. Independently corroborated by the official store's own variant weight of 14,061 grams.

No Limit When Wiring in Parallel
Official datasheet (PDF) — An affirmative statement that no limit exists, which is different from a limit simply not being stated. maxInParallel is left null because this numeric field cannot express it.
